OAI-PMH Architecture for the NASA Langley Research Center Atmospheric Science Data Center
نویسندگان
چکیده
We present the architectural decisions involved in adding an Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) interface to the NASA Langley Research Center Atmospheric Science Data Center (ASDC). We review four possible implementation strategies and discuss the implications of our choice. The ASDC differs from most OAI-PMH implementations because of its complex data model, large size (1.3 petabytes) of its Earth Science data holdings and its rate of data acquisition (>20 terabytes / month).

OAI-PMH Repository Enhancement for the NASA Langley Research Center Atmospheric Sciences Data Center
The NASA Langley Research Center Atmospheric Science Data Center (ASDC) has almost 2 petabytes of canonical earth science data. Despite this volume of data, the ASDC does not maintain the information resources derived from this data: publications, web pages, visualizations, etc. We present the preliminary results of a project that augments the holdings of the ASDC by using search engine APIs to...

متن کاملMeasurements, Models, and Hypotheses in the Atmospheric Sciences
Measurements in atmospheric science sometimes determine universal functions, but more commonly data are collected in the form of case studies. Models are conceptual constructs that can be used to make predictions about the outcomes of measurements. Hypotheses can be expressed in terms of model results, and the best use of measurements is to falsify such hypotheses. Tuning of models should be av...
